This article discusses the issues of histogenetic recapitulation and autonom migration of myogenic cells in the embryogenesis of Snake-eyed lizard. It has been established that the formation of Snake-eyed lizard somites is observed 3-5 days before incubation. Segmentation of myotomes from somites is observed in the cranio-caudal direction. In the future, myoblasts begin to autonomously migrate to the area where the future muscles are located and multiply intensively under the influence of growth factors. At this stage, the differentiation of myogenic cells occurs using the genetic information and the first signs of differentiation appear.
